INTRODUCTORY ESSAY. 71 Range of the Punjab, and another from the Marri hills be- tween the Jelam and the Indus. 32. Mr. Lance's Kashmir and Tibet collections, communi- cated through Mr. Edgeworth. 33. Dr. Jameson's collections from Massuri and the Saha- ranpur Gardens. As, however, we are so largely indebted to the floras of coun- tries bordering upon India for the elucidation of our Flora, it is necessary to add that the Hookerian Herbarium is as rich in proportion in the plants of surrounding countries as it is in Indian. Of these, the most important are the following:— A. From the Malayan Archipelago and China. 1. Cuming's magnificent Philippine Island collections, con- taining about 3000 species. 2. Lobb's Java, Borneo, and Philippine plants, which are very mimerous and in excellent preservation. 3. Extensive Javanese collections, communicated by Pro- fessors De Vriese and Miquel. 4. ZoLUnger^s Javanese plants. 5. Spanoghe's plants from Java and Timor (not numerous). 6. Professor Blume has communicated authentically-named specimens of a very few Javanese and Molucca natural orders: these are extremely valuable, especially the Anonacea and Cupulifera. 7. Mr, Motley's extensive Borneo collections. 8. Mr. Lowe's small collection from the same island. 9. Dr. Seemann's Malayan and Chinese collections. 10. Major Champion's Hongkong herbarium, which has been described by Mr. Bentham in the c Florida Hongkong- ensis' in Hooker's Kew Journal. 11. Mr, Millett's Macao plants. 12. The Rev. Mr. VachelPs Chinese collections. 13. Captain Beechey's plants from China, collected by Messrs, Lay and Collie, and described in the 'Botany of Beechey's Voyage.'
